In figure：1 front surface, 2 rear surfaces, 3 left surfaces, 4 right flanks, 5 bottom surfaces, 6 bottom adhe bars, 7 side adhesive strips, 8 Sealing strip, 801 thin wires, 802 sealing strip bonding parts, 803 bodies, 9 observation windows.

Embodiment

It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

As shown in Fig. 1-Fig. 7, a kind of paper bag easy to use, is formed, plane is unfolded in the scraps of paper by scraps of paper bonding folding Including long on the right side of the front surface 1 being split to form by folding line, the left surface 3 being connected with long side folding line on the left of front surface and front surface Right flank 4 that side folding line is connected, the rear surface 2 being connected with left surface long side folding line, the bottom surface being connected with each face short side folding line 5, the bottom adhe bar 6 being connected with 5 long side folding line of bottom surface and the side adhesive strip 7 being connected with right flank long side folding line, the scraps of paper Inner side is covered with a tunic, and scraps of paper rear surface 2 or 1 top of front surface are equipped with sealing strip 8, by bottom adhe bar 6 by bottom with Front surface 1, left surface 3, right flank 4,2 lower part of rear surface are connected as sealing structure, by side adhesive strip 7 by right flank 4, after Surface 2 is connected as sealing structure.The utility model bonds folding by the scraps of paper and forms, on the one hand into can be once during production Punch forming, convenient production, the on the other hand not compact influence of convenience in transport in transport.

As shown in fig. 6, sealing strip 8 includes bar body 803, some has certain rigid band elastic body 801, sealing strip bonding Portion 802, band elastic body 801 can be metal or nonmetallic strand, thin slice, and sealing strip bonding part 802 bonds in the rear On surface 2, band elastic body 801 is connected as one by modes such as bondings with 803 middle part of bar body, and sealing strip 8 is than rear table Face 2 short side length.The bar body portion of 801 liang of outside lefts of band elastic body can be rectangle paper slip.Since sealing strip 8 is that have two slips Body 803 is bonded with the isostructural band elastic body of thin wire 801, if producing inconvenience by thin wire by one-pass molding 801 insert, so being pasted onto rear table using adhesive after sealing strip bonding part 802 by individually producing and increasing sealing strip 8 This mode manufactures on face, can simplify process, reduce cost.

The film is a kind of damp-proof membrane, and one layer of damp-proof membrane is covered on the inside of the scraps of paper can be effectively increased scraps of paper intensity, and play The effect of food in protective bag.

The damp-proof membrane is PE films, and PE films have appropriate oxygen permeability and moisture permeability, can adjust in paper bag the oxygen of food and The content of moisture, obstructs dust, so as to extend the freshness date of food.

As shown in Figure 1, paper bag front surface 1 is equipped with observation window 9, due to being covered with one on the inside of the scraps of paper used in the utility model Tunic, so increasing observation window 9 on the scraps of paper of front surface 1 does not interfere with holding for food, and is conducive to directly perceived to customer Product is sold in ground displaying, is conducive to sell.

Bottom adhe bar 6 is regularly stamped with bump mark 61, and increasing bottom adhe bar 6 by this structure of bump mark bonds Intensity afterwards, greatly increases the ability to bear of paper bag bottom.

Businessman logo and advertisement are printed on paper bag, on the one hand the utility model carries packaging as a kind of package packing supplies The effect of itself, is on the other hand also used as a kind of free advertising to publicize businessman, reaches two-win.

As shown in Figure 1, the utility model can pass through bottom adhe bar 6 and side adhesive strip 7 in production with one-pass molding After bonding, the utility model becomes as shown in Fig. 2, since the utility model is per se with folding line, after simply being folded by folding line, Become as shown in figure 3, on the one hand this structure shown in Fig. 3 is conveniently transported to convenient using businessman, another aspect from manufacturer Businessman uses, it is only necessary to simply struts state as shown in Figure 4 and can be used, after being put into food, by front surface and rear table Face and sealing strip while downwards curling, then grow sealing strip both sides before and after being partly bent upwards or being conveniently open Position, state as shown in Figure 5, due to carrying thin wire in sealing strip, so if no longer applying power after sealing strip stress and deformation Original shape would not be become again, so as to have the function that sealed opening., can be always at the same time with the reduction of article in paper bag Curling downwards keeps the diminution of internal volume, to reduce the air of space hold and inside, to extend the storage life of food, avoid The short-term endometamorphism of food after bag is opened, beneficial to the mouthfeel for keeping food.

Obviously, described embodiment is the part of the embodiment of the utility model, instead of all the embodiments.It is based on Embodiment in the utility model, the institute that those of ordinary skill in the art are obtained on the premise of creative work is not made There is other embodiment, shall fall within the protection scope of the present invention.
